Section 3 • Living Soil, Integrated Soil Nutrient and Crop Managements
• Indigenous microorganisms (IMO) enhance growth and productivity of crops. These include
known soil microbes such as mycorrhiza and Rhizobium, biological nitrogen-fixers, which fix
and convert air nitrogen to nutrient forms readily available to plants and can substitute 30-50%
of plants’ nitrogen requirements. These microorganisms are now mass-cultured and massdistributed
to farmers.
Such doable innovative strategies can be shared and enriched by farmers and facilitators in FFSs to
improve current soil and organic fertilizer management practices through participatory, discoverybased,
and experiential learning approaches, hence this exercise.
How long will this exercise take?
• One to two hours for field walks, observations, interaction with farmers and hands-on in learning
field
• Thirty minutes to one hour for brainstorming session in processing area
learning objectives
• To create awareness and understanding among participants on some innovative organic foliar
sprays as plant nutrient supplement for organic solid fertilizers in organic vegetable production.
• To learn from others and do actual preparation and use of these organic foliar sprays as plant
nutrient supplement for organic solid fertilizers in organic vegetable production.
materials
• Office supplies (e.g., Manila papers, notebooks, ball pens, marking pens, and crayons)
• Organic vegetable crops applied with organic solid fertilizers that are ready for supplemental
organic foliar spraying in learning and adjoining fields
• Other supplies (e.g., knapsack sprayer, table spoon, shovel or spading fork, tape measure, bolo,
or scythe) and the following:
